Out of Storage After 35 Years - Couple Questions

No way I'd go to all the trouble of putting that engine in a car without checking it out completely first. Even if you can run it out of the car, I'd for sure pull the pan, check bearings, pull the timing cover(there's bound to be some corrosion there), new timing chain if needed, install new brass freeze plugs, and new gaskets and seals. If you can do a compression test out of the car, I'd do that too. At least do a psuedo- leak down test with an air hose to see if it has any major burnt valves.
